From the post
Here's one from MXR you probably haven't heard of before. It was apart of their Commande line of plastic boxed effects from the late 80s. They aren't highly regarded because of the plastic, but the circuits were pretty well designed. The circuit in question today is a better design than the DynaComp, offering less distortion and more sustain. It does have a little less compression range than the DynaComp, but also less noise. (And really, who needs that much squish? haha) Couldn't find a demo of this one, but the schematic and discussion can be found here on FSB.
